Farpoint Bahtinov Focus Mask Snap-in for DSLR with 62mm diameter filter

Like illustration. (Stand not included)

The unsharp mask according to Pavel Bahtinov facilitates precise focusing, which is particularly important in astrophotography. The mask is attached to the front of the tube or lens. When looking at a star, it creates a radiation pattern. If the long beam intersects symmetrically with the two slightly shorter ones in the middle, the focus is set correctly. Due to the numerous opening slits, the Bahtinov mask can also be used on relatively faint stars. This is an advantage over the classic Scheiner screen.

Description

Actually, a separate Bahtinov mask would have to be calculated for each aperture ratio. However, experience shows that a mask can be used very well for a full opening area.

How the Interchangeable Lens Camera Mask Works: The Bahtinov mask fits over any standard lens filter. Regardless, many photographers already have a UV filter or other screw-on filter. The mask can be inserted into said filter with a simple click. The filter with the inserted mask is then screwed onto the front end of the lens as usual through the filter thread.

Please note the diameter of the Bahtinov mask in the product title. You must choose the mask that matches the filter diameter of your lens.

Bahtinov's unsharp mask works best at long focal lengths. Your lens must have a focal length of 100 millimeters or more.

Please note: The product image above shows how it works. Of course, the scope of delivery only includes a Bahtinov focusing mask and no lens filters!
